Question

Is the point (-3,5) contained in the solution set of x+2y>7. show your work.

Answer 1

So, we must put the points (-3,5) into the solution x+2y>7

X is -3 and Y is 5 so we just put them in place...
-3+2(5)>7
-3-10=7
So I mean no, technically... it would be x+2y=7

Answer 2

the answer is yes because  you substitute -3 with x , 5 with y . so (-3+2(5)= 2 times 5 =10 . so -3+10 =7.
